Product Description

The fundamental design of this new generation of Denso Iridium Power spark plugs retains the proven features used in Denso's OE products and combines a revolutionary Iridium alloy with laser welding technology that allows Denso to harness the power of Iridium. Using Iridium, which is six times harder and eight times stronger than platinum, the tip can be shrunk to only 0.4mm. This means the voltage requirements are decreased while firing performance is greatly improved. A U-Groove has been cut inside the ground electrode to maintain the large volume of space required to form the nucleus of a flame. While still keeping the required voltage low, this powerful technology enables excellent firing performance without increasing the spark gap. The tip of the ground electrode has been cut to form a taper. This greatly improves firing performance by reducing quenching. The extreme hardness and high melting point of Iridium prevented the use of this incredible metal until Denso perfected the Laser Welding Process, which provides a 360° seal so reliable the electrode resists wear even in the harshest conditions.

Warranties:

All Products sold by SPEED PERF6RMANC3 are covered by the manufacturer's own terms of warranty. SPEED PERF6RMANC3 is not responsible for products sold which are not covered by a manufacturer's warranty. Some vendors, such as Ford Motorsport Racing, do not offer any form of warranty on their products. For warranty information on specific manufacturers contact the manufacturer directly.

Failure to return the shortblock / longblock for warranty consideration/inspection releases SPEED PERF6RMANC3 from ALL warranty obligations. Because SPEED PERF6RMANC3 does not manufacture many of the parts contained within these engines we cannot provide a warranty for them, the individual manufacturers of these internal parts may have warranties, because they change from time to time it is best that the customer contact these companies for up to date information. Warranty is only valid to original owner. Service records required showing proper maintenance.

Extended Warranty: When the extended warranty option has been purchased the warranty is extended from the above 6 months to an additional 1 year for a total of 1 year and 6 months (1 1/2 years).

A Note On Engine Builds

It is very important to understand the differences between OEM and Forged pistons, and what an appropriate application to use them in is. The majority of our customers drive their vehicles daily, and therefore reliability is always a factor to consider when building a street-engine. The single best way to stay very reliable and make good "useable" horsepower, is to use OEM pistons in your build. Forged Pistons are not designed to be used in a daily driven application. Forged pistons are designed to be used in a race engine where they are checked from top to bottom and rebuilt if needed after a specified number of races. Anyone who builds a street purpose motor has no intentions of tearing it down every 10k miles just to see how things are doing.

The reliability factor between OEM and forged pistons is in the material and how it behaves. Forged pistons are made from two different alloys, 2618 aluminum alloy and 4032 aluminum alloy. The difference is that 4032 has more silicone built into the piston, allowing for LESS thermal expansion, and allowing you to run a tighter piston-to-wall clearance (PTW). Piston-to-wall clearance is the area between the piston and the cylinder wall. This clearance is built into the bore so the piston can expand correctly. 2618 aluminum alloy has less silicone and expands much more than 4032. However, 2618 has proved to be stronger and can take much more abuse (detonation). Under detonation the ring lands become brittle and crack in 4032 alloy pistons. The disadvantage to having 2618 alloy is because of the loose piston-to-wall clearance that must be run. Typically, most manufacturers of 2618 alloy pistons require a wall clearance of .0030 to .0045in. (3 to 4 1/2 thousandths of an inch). When it is this loose, there will be a considerable amount of "piston slap". When you first start the engine and it is cold, you will hear the pistons rocking back and forth in the bore, giving off a clackity sound. As the engine warms up, this sound will diminish or disappear entirely, depending on the clearance.

Imagine this event in a daily driven engine. The car is started on an average of 2-4 times a day. Multiply that by a number of days, then weeks, months, etc. What ends up happening is your blocks cylinder walls become "chaffed" and "out-of-round" which leads to improper sealing and oil consumption. All of this can happen on your engine build after only 15- 20 thousand miles. Race teams understand this and use the piston for what it is intended. OEM pistons are used in many autocross and road racing applications and should be used in your street builds. OEM pistons are used in road racing over forged pistons, because of the effective sealing properties and reliability that they provide.
